X-7 MODULAR  BALANCED ROTATING ASSEMBLIES
4.6/5.0/5.3 Big Bore/5.4
The Modular rotating assemblies use the same type of high quality parts as our other X7 rotating assemblies, but use a KPC Race micro alloy forging in place of the 4340 steel crankshaft which do no require the rod bearing to be CNC chamfered.  Because of the smaller journals the connecting rods use a 3/8" ARP cap screw, which is made from ARP2000 material.
